US 10,864,335 B2 · System, apparatus and methods for supplying gases

Abstract

A system, apparatus and methods are provided for supplying gases to a user. The supply includes a sub-therapeutic mode and a pressure support mode for delivering therapy to a user. A flow diversion device or valve switches from a first mode corresponding with the sub-therapeutic mode of the system to a second mode corresponding with the pressure support mode of the system. In the first mode, the valve opens a larger flow path between the interior of the user interface and ambient air than in the second mode.

Dependent claims

A system configured to supply respiratory gases to a user wearing a user interface, the system comprising:

a flow generator;
and
a controller controlling operation of the flow generator, the controller configured to:
operate the flow generator in a first mode to create a first pressure that is below a therapeutic pressure range;
operate the flow generator in a second mode to create a second pressure that is within the therapeutic pressure range;
and
transition from the first mode and the second mode in synchrony with inhalation of the user,
wherein the controller is configured to transition from the first mode to the second mode when the user is determined to be asleep, and to transition from the second mode to the first mode when the user is determined to be awake.
